Nikon D7100 preview

“Superior Clarity and Nimble Precision: The DX-Format Nikon D7100 embraces the advanced enthusiast with intuitive engineering” - As titles for press releases go, this one from Nikon is quite a mouthful. Announced on 20th February 2013 and sitting in the mid-range of the Nikon camera line-up, the D7100 bares a strong resemblance to the very popular D7000. However, the similarities are only skin deep as the D7100 internals are heavily modified and Nikon are billing it as their “flagship DX-format” camera.

SENSOR

The most obvious, and indeed forward thinking, difference between the D7000 and the D7100 is the complete removal of the optical low-pass filter (OLPF) from in front of the sensor. These filters are traditionally used to help combat moiré patterning seen when photographing patterns or fine detail. However, the trade-off is that they also reduce the clarity, or sharpness, of your images and HD video. It’s similar to the trick Nikon pulled with the D800 and the D800E, except where they had two models, one with the filter and one effectively without a filter (D800 and D800E respectively), here there is just one model. Unlike the D800E instead of the filter effect being ‘removed’, it simply doesn’t have the filter fitted to begin with.

You may feel that avoiding moiré patterns is a good thing and therefore the filter is worth keeping, however Nikon believe that the pixel density of this all-new 24.1megapixel DX CMOS sensor is such that the risk of moiré is substantially lower and therefore the benefits of increased sharpness and resolution win out.

CROP MODE

Beyond the resolution, the Nikon D7100 is able to shoot at 6fps in normal mode, or 7fps in a new crop mode. The DX sensor is normally APS-C sized, however this crop mode reduces the effective size of the sensor by 1.3x giving the equivalent of a 2x crop in 35mm terms, so a 100mm lens has the same field of view as a 200mm lens. The resolution is also reduced in this crop mode, dropping to 15.4megapixels. If you’re interested in wildlife or sports, or always find yourself wishing you had a longer lens, this may well be a great benefit.

FOCUSING

Another sign of the changes that have taken place under the hood is the new AF system. The D7100 uses the Multi-Cam 3500DX AF sensor that features 51AF points of which the central 15 points are cross-type for improved accuracy and focus speed. In another nod to sports and wildlife photographers, the AF sensor will function with a maximum aperture of f/8, so an f/4 lens with a 2x Extender is not a barrier to autofocus performance.

The placing of the AF points has also been carefully thought out – when the 1.3x crop mode is selected, the 51AF points will cover a much larger part of the frame giving you flexibility in selecting AF points out to the edges, and equally improving subject tracking across the frame.

HD VIDEO

HD Video is now firmly established as an important feature in every new DSLR and the D7100 is no different. A dedicated video recording button makes it quick to access. Video can be shot at 30p, 25p and 24p in Full HD (1920x1080) or at 60i and 50i if you switch to the 1.3x crop mode. 50p and 60p shooting are also available, but only at 1280x720.

There is also an internal stereo microphone and a headphone port to allow live audio monitoring while filming – something that’s very important when recording audio on-camera.

SPOT WHITE BALANCE

Another new, and very interesting, feature is the Spot White Balance option. While shooting in live view you can select a point on the screen and take a custom white balance from that area. If you’re using long lenses or don’t have a grey card to hand, this could prove very beneficial in achieving accurate white balance both for stills and movies.

CONNECTIVITY

If you need to share your images with the world as quickly as possible, the D7100 can be attached to the optional WU-1a Wireless Mobile Adaptor. This allows you to share your images with a smartphone or tablet, or control your camera from the remote devices using an app available for Android and iOS.

BUILD AND DURABILTY

Rounding out the key features of the D7100, the camera shows its true aims with a robust construction that uses magnesium alloy for the top and rear covers and a shutter life tested to 150,000 cycles. The dust and moisture resistance is also much improved compared to the D7000 - Nikon are claiming it is to the same level as the D300S.

The viewfinder is also new, featuring an OLED data display to make it easy to see shooting settings in a wide range of light conditions. The viewfinder also features 100% coverage so you won’t accidentally miss twigs sticking into the edge of the frame. The addition of dual SD card slots is another interesting development

Inconsistent classifications

The D7100 was classified as a "Semi-Pro" DSLR and yet the Pentax K3 has more useful features including full weather sealing and is considered by DXO an "Entry-level DSLR" camera. Please explain the rationale/criteria when classifying the cameras or do you folks arbitrarily bin products for no specific reason. Thanks

Sony A99 has a much higher score than the ISO that you specify

Your rating ISO is completely wrong!Sony A99 has a much higher score than the ISO, which you state your lab tests around the SLT are misleading and reflects micro differences eye and do not perceive the SLT greatly underestimated.

It seems someone painting on the same high ISO 7100 vs A99?

ISO 1600 at 7100 already in JPG visible noise, the A99 anything.ISO 3200 in 7100 noise is no more evident for A99 small changesISO 6400 in 7100 image was far more noisy at A99 level as in 7100 iso 1600!ISO 12800 in 7100 to significantly increase noise compared to the A99, which is still applicable.

RAW same ...

You write and publish half-truths.The problem is that the A99 has LOW LIGHT-ISO 1550 but over 2000.

Anyone can look at the samples! and really looking to compare 1:1.http://www.dpreview.com/reviews/nikon-d7100/21

Hello!

Thanks for interest in DxOMark.

The DxOMark sensor score only evaluates RAW image quality on the sensor noise point of view. The comparison is a JPEG comparison, with a raw convertor that could have slight different behavior between the different cameras. The ISO lowlight score of the SLT A99 is pretty good and is a third stop better than the last Nikon D7100.

Is not a big diference between D7000

Upgrade from D7000 to D7100 not worthUpgrade from D7000 to D600 worthUpgrade from D90 to D7000 worthUpgrade from D90 to D7100 Totally worthUpgrade From D90 to D600 Totally WorthUpgrade From D300 to D600 Totally WorthUpgrade From D300s to D7100 Worth

if you have to choose between the d7000 or d7100 go for the d7100 if money is not a problem spend 800$ and get the d600 but if you wanna save 300$ and get a better lens get the d7000

It is not a must have upgrade for those who currently have a D7000 but, if you shoot a lot of video it becomes something you may well want to consider.

Re: Is not a big diference between D7000

Apologies, Just a quick question... Have you taken the time to really examine the differences between the 7100 & 7000? Because your advise is inaccurate... There are huge differences between these 2 cameras!!! Giving it worthy consideration to an upgrade from a D7000.

I tell you what, when DxO releases the official scores for lenses, coming soon btw, I will bet one of my D800's that you will retract that statement, and thank me for sending you out to go add one to your camera bag!!!

Re: Is not a big diference between D7000

ThatNikon Guy

I'm not saying that the d7000 is better I'm just saying the upgrade to the d7100 is not worth for the money and if you dont own any i will say go for the d7000 because is better for the money you can buy better lens that will give better result,compare to the d7100 with the start kit lens

now tell me something would you get the d7100 if you own a d7000

What is better have better camera with standard lens or standard camera with better lens

Re: Nikon D7100

Dude, DXO Mark are pro, every pro photographer appreciate and guide their choices on their tests, do you think they would deliberately downsize the mark of D7100? what in it for them? i believe that this test is right. Anyway, D7100 is a great camera with a good AF system and a great IQ even if it is worse than D600's IQ... which is a full frame camera.

Re: Debate with Thai Nikon Genius!

After i bought D600 i was disappointed by the autofocus (on the paper, in real life works great, better than D7000's) and i wanted to buy the D800. I am happy i didnt. I am sure that in time you will really start to love the D7100 because it gives you everything you need to make great photos... if you are not a failure as a photographer :D
